HORSESHOE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 412,497, dated october8,1889.

Application filed May 1, 1889.

serial No. 309,187. (No modal encebeing had tothe accompanying draw-Figure l is a side view of my improved horseshoe-hammering machine. Fig.2 is a plan'view. Fig. 3 is a transverse section on the line 1 2,Fig. 1. Fig. 4 is atransverse'section on the line 3 4, Fig. 1; and Figs.5, 6, and

` 7 are enlarged views of the horseshoe-blankholding mechanism.

A is the frame 4of the machine,l on which is mounted the tableB,carrying the horseshoe- ,blanks` This table slides on Waysa a on theframe, and has a projection which passes through a longitudinal slot inthe frame. The

table B is hollow in the presentinstance, and has two or more nipples,to one of which may be secured the inlet-hose and to the other theontletfhose for the Water, which acts to cool the/table during theworking of the" machine. Secured to the projection f the table B is avknee C, having a face' c', against which acts theroller d, describedhereinafter. This roller vmoves the table in the direction of the arrow,Fig.l 1. i In the rear end Vof the table is secured a hook e, to whichis fastened a chain or cord e', which passes over a suitable pulley e2on the rear end of the frame of the machine, and to this cord isattached a suitable weight yE for returning the carriage to its originalposition, thecarriage coming against suitable stops a', having yieldingbuffers a2 of rubber or other elastic material.

In bearings in the frame of the machine is a shaft F, having two disksD'D secured to it, and tying these two disks together is a bolt d',carrying the roller d, mentioned above. This roller is placed 0E center,as shown, so that as the shaft revolves the roller will force the tablein the direction of its arrow, Fig. 1, until it is released from contactwith the roller by the roller passing away from the Will be brought backby the Weight described to its original position. The shaftF is gearedto a shaft vD by means of a gear-Wheel f and pinion f. The shaft D is'inturn geared to a sleeve H, carried ,by the shaft F through the medium of"a wheel and pinion' g g', this pinion g being secured to the sleeveH,`Which driving-pulley I-I. as shown, be a combined fastan'ddoosepulley or a plain pulley. y

I I are ltwo housings, mounted on the frame A of the machine, and thesehousings are proi vided with suitable bearings i, adjustable in ,saidhousings by'nieans of a set-screw 2. The `bearings support the shaft J,which has na drivingpulley J on one side and carries :rolls M, whicheither revolve freely around the axle or shafts K or are secured totheshafts which would revolve in the hbearings in the frame.

It may be mentioned here in the outset that the shaft J isspeeded Iso'asvto' allow'the hammers M to strike the shoe in rapid succession whilethe shoe travels through the machine slowly on the carriage or table B.On the table is a suitable die N, secured to said table by bolts fn..This die can Abe removed and replaced by one of different size whencircumstances require. On this die are 'fof the contour of the outsideheel portionfof the shoe. These projections lextend to or nearly to thecenter of the shoe, as shown.

i I P are two leverspivoted at p, and having arms p p2. The arms p areturned outf ard, 4as shown, and press against the inner heel portion ofthe shoe, While each arm p2 has a roller q, which bears against acam-face on a plate Q, which is 'adjustably secured to the frame of themachine by bolts r r, which justing-screws q2 bear against the back ofthe plates to set them up to the required point. Each cam-plate has aflat portion s and'inclined portions s S2, one at the rear and the othertwo projections m m, having their inner faces f at the front. The leversI P are kept against knee. Immediately on its release the table ,caneither be secured to or form part of a The driving-pulley may, t

al frame K, in Which are bearings for shert shafts or spindles K',carrying hammermgpass through slots q in the said plates. Ad-

IOO

these cam-faces by springs t t, secured to the pivots p, and bearingagainst pins or lugs t on the arm 152 of the lever.

When the carriage is in its normal position-that is, from under thehammer-the rollers on the levers P P rest in the depressions formed bythe inclines on the camplates; but when the machine is going forward inthe direction of the arrow, Fig. 1, and is under the hammer, the leversare pressed hard against the inside of the shoe, as shown in Fig. 2,holding the shoe fast, and the shoe is not released until the rollers onthe levers are released, when they reach the inclines s2.

b is a projection which extends from the die directly back of the toeportion of the shoe, and enables the attendant to place the shoe in theright position on the die. In the die is a supplementary die T, havingthe shape of the toe portion of the shoe, as shown in Figs. 2 and 5, andhas portions u,which are beveled to give the required bevel to the underside of the shoe.

The shoe hammered on this machine is a plain shoe, and creased and bentbefore hammering. In bending a creased shoe a portion of the material ofthe shoe is thrown up around the inner curve of the shoe, and this mustnecessarily be flattened, so that the face of the shoe will be perfectlyfiat. To Hatten this face is what this machine is intended for, and atthe same time the necessary bevel is formed on the under side of theshoe, in order that the shoe may fit snugly to the horses hoof. Thishammering also alters t-he inclination of the nail-holes to the anglerequired.

The shoe is removed from the machine automatically by the device which Iwill now describe.

Secured to one of the housings of the frame is a bracket V, throughwhich passes a rod V', a set-screw u on the bracket holding the rodsecurely after adjustment. On the end of the rod is a socket W,'throughwhich passes the shank w of a head w. This shank is adjustably securedby means of a set-screw w2 or by a uut on the shank, or both. To thehead W is pivoted a finger W', beveled on the inner side and allowed toswing only in one direction, as indicated by the arrow, a stop wpreventing the swinging in the opposite direction. The finger is in sucha position in respect to the shoe to be hammered that as the table movesforward and passes under the hammer the shoe hits the finger, moving itup, the shoe passing under the 1inger sufliciently to allow the fingerto drop to its normal position and back of the toe portion of the shoe.The shoe being released at this point from the control of the levers P Pl is held by the finger and prevented from re turning with the table,and as soon as the table recedes the shoe will fall onto the inclinedribs A', which direct it into a suitable receptacle or onto the oor.

I claim as my invention- 1. The combination, in a horseshoe -ham meringmachine, of the hammers, the traveling table carrying the horseshoes tobe hammered, said table having a projection or knee with which engagesan arm on a disk or disks secured to a power-driven shaft, substantiallyas described.

2. The combination of. the hammers, the moving table, mechanism formoving the same, said table carrying the horeshoe, pivoted levers forholding the said horseshoe on the table, with cam-plates so cut as tohold the shoe as it passes under the hammer and to release the shoe atthe end of both the forward and backward movement, substantially asdescribed.

3. The combination of the movable table having projections of thecontour of the outside heel portion of the shoe, and having leverspivoted to said table, one arm of each of said levers bearing againstthe inner portion of thel shoe and the other arm bearing upon thecam-faces of the cam-plates, the whole acting substantially asdescribed.

4. The combination, 4in a horseshoe-hammerin g machine, of the travelingtable, an d the hammers, with a beveling-die situated on the table in aposition directly under the front portion of the shoe to be hammered, sothat said shoe will receive the necessary inner bevel, substantially asdescribed.

5. The combination of the table, the hammers, mechanism for operatingthe hammers and table, with a die for the shoe to be hammered, devicesfor retaining the shoe on the die with the finger pivoted to the head,so that the shoe to be removed can ride under said finger, but will bewithdrawn on the return movement of the table, and devices for releasingthe shoe on its return movement, substantially as described.

6. The combination, in a horseshoe-hammering machine, of the hammerswith a travcling table carrying the shoe to be hammered, said tablehaving water-passages, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
